ABB SD Series Comprehensive I/O product portfolio

SD Series

Comprehensive I/O product portfolio

The SD Series I/O product family includes DIN Rail horizontally or vertically mounted digital

and analog modules, as well as integration with intelligent field devices and protocols using

PROFIBUS DP, HART, IEC 61850. IEC 60870-5 104. DNP 3.0. and Modbus TCP communications.

Hardwire I/O and fieldbus I/O coexist and use the same function block library to build real-time

control applications.

Traditional SD Series analog input modules interface with field inputs such as pressure and

flow transmitter signals, thermocouple inputs, and resistive temperature device (RTD) inputs.

Analog output modules provide output signals to adjust final control elements such as control

valves, positioners, actuators, etc.

SD Series digital input modules have input channels to read the states of switches, relay

contacts, solenoids, etc. Digital output modules provide output channels for DC or AC switching

applications. The digital outputs can be used to drive annunciators and to drive two-state final

control elements such as actuators, relays, and solenoids.

For SD Series Digital I/O, each channel can be individually configured as an SOE (Sequence of

Events) point. This flexibility removes the cost and complexity of assigning additional digital

inputs as SOE in the field. SOE with 1 msec timestamp is available across the entire system,

whether the I/O is local or remotely located.

Redundant I/O

SD Series redundant I/O arrangements provide enhanced availability for your most critical field

I/O.  Available for both analog and digital I/O, these redundant I/O modules protect against

common power, communications, hardware and software failures and I/O channel failures without

requiring any additional configuration.

Local and remote options

24V DC power requirements, low module power consumption, and a module temperature rating

of -40°C to +70°C (ambient) make SD Series I/O equally suited for local or remote I/O installations.

G3 coating makes SD Series I/O suitable for use in corrosive environments without requiring costly

sealed cabinets or purging systems. The software configuration is identical when configured as

either local I/O or remote I/O or mixed.

Easy expansion of existing Rack systems SD Series I/O modules are compatible with HR

Series BRC300/400/410 controllers for easy, incremental expansion of existing Rack systems.

Typical examples include expansion with remote I/O or HART enhancements to existing Rack

installations.
